The gorgeous crystal lamp casts a slightly dim light. In the center of the spacious dining room is a long dining table for more than a dozen people to eat. It is paired with a simple but charming high-backed chair. The walls on all sides are decorated with huge Western oil paintings. Everyone sits around the dining table and smiles.

"I'm going to start~" A few little radish heads looked at the wide variety of food on the dining table and were already salivating, and the knife and fork in their hands were already hungry.

"Hahahaha~ It's good to be so lively occasionally." Mr. Aman sighed with a smile.

"Yes, since my mother died in that fire, there have been almost no guests here." The noble master agreed.

"But, I heard from the servants that you two have been here since the fire. Why is that?" Dr. Agasa asked curiously, holding the thin handle of the goblet in his hand.

"Actually, I originally planned to return to this castle after graduating from university." The noble young master gently answered Dr. Agasa's doubts.

"I was at first worried that my mother-in-law, who lost her only daughter, lived here, but as I lived, I became more and more fond of this castle where my wife was born and raised." Mr. Aman couldn't help but fall into memories.

"Hmph-I think you don't like this castle, but the treasure hidden in this castle, right?" The old lady sitting in a wheelchair looked gloomy and sarcastic in her hoarse voice.

"Extra...grandma."

The noble young master looked embarrassed, but the identity of Mr. Aman, who was even more awkward, didn't care and said with a smile:

"That's true. If I don't care about my father-in-law's last words, I'm definitely lying."

Gu Shuiquan couldn't help but sigh in his heart that this person was a figure, not only inheriting the Prime Minister's taste, but also inheriting the Prime Minister's openness (fog).

"I knew that my daughter was deceived by a greedy guy like you. I want to have dinner in the room. When my daughter arrives, I will bring her over. I must talk about her." After saying that, the old lady flexibly moved her wheelchair and left.

"Grandma is still the same as before. She always thinks my mother is still in the world." The noble master sighed.

"It's no wonder she has a bad memory. It's been ten years since her feet started to hurt. She has been trapped in this castle for many years and has not gone out." Mr. Aman explained, then turned to look at Tani Mizuto, who was picking up food for Ai Haibara. "By the way, Mr. mystery novelist, have the puzzle been solved?"

Tani Mizuin gave food to Ai Haibara on her plate and said calmly: "I haven't seen it yet, but it should be easy. As long as you know something, you can untie it immediately."

"oh???"

"Really???"

"Are you saying true??"

Master Aman and the noble master stood up excitedly, and the old lady suddenly appeared in the restaurant again.

The old lady's control of the wheelchair became even more amazing. She quickly and flexibly pushed the wheelchair to Gu Shuiquan's seat, staring at him with her eyes tightly and holding his back firmly with her hands.

"What is it, what is the answer to the puzzle? Where is the treasure hidden in the castle? Hurry up, tell me!"

The old lady was so anxious that Tanizumi still slowly picked up food that Haibara Ai couldn't reach, and then slowly said, "It's time to eat now, so it's not suitable to talk about these things. It's better to wait until you have eaten, and it's not a short time. For children, dietary rules are very important."

The old lady still wanted to say something anxiously, but Mr. Aman spoke first.

"My mother-in-law, isn't Mr. Gu here? It's not a short while. You can't ask the guests to solve any puzzles halfway through the meal. That would be too rude, do you think?"

"Yes, grandma, don't worry, you can eat something first." The noble master echoed.

After hearing the two of them, the old lady stopped urging Gu Shuiquan to hurry up, but she refused to go to her own place to have a meal. She stared at Gu Shuiquan's figure there.

After a while, Haibara Ai put down the tableware in his hand and said, "You'd better solve the puzzle for them first. I really can't eat this."

The two old men over there seemed to be eating normally, but they didn't eat a few bites of the meal, but their eyes glanced at this from time to time. There was an old lady with crane hair and chicken skin behind her, which was really hard to have an appetite.

"All right……"

Gu Shuiquan wiped his mouth. When he stopped, the three most excited people couldn't sit still. They couldn't help but gather around and stopped talking about etiquette.

"Xiao Ai, do you still remember the layout of the chessboard in the yard?"

"Well, I remember that I saw Conan's records in the notebook before, and I can't forget them all." Haibara Ai raised his little face and smiled slightly, as if he was looking for a little praise.

"Well, that's really a big help." Gu Shuiquan touched her cat's head, who sat honestly without any intention of avoiding it.

"Ah, I'll go and get paper and pen."

Master Aman ran to pick up paper and pen with a wink, but saw him swaying with his head held high and his steps were vigorous. Although he was still walking, he always gave people the illusion that he was about to take off.

In the blink of an eye, he flew back and placed the paper and pen very kindly on the table in front of Ai Haibara.

"What a smart little girl, I remember it after just one look."

While complimenting, he tried to reach out to touch Haibara's head like Tanizumi. However, as soon as his hand was raised, Haibara Ai threw a cold look at the inferior creature, causing him to froze.

"Hahahaha~ He's really a child with personality." Mr. Aman had to touch the back of his head with his hand, not caring about the embarrassing situation just now.

In fact, no matter how embarrassed he was, no one would pay attention to him. Everyone's eyes were gathered on Gu Shuiquan, who was dressed in black, waiting for him to uncover the puzzle that had troubled them for many years.

Haibara Ai quickly reproduced the position of the chess piece recorded by Conan on the small notebook and the letters marked around the chessboard lattice on the paper, and handed them to Tani Mizumizuki beside him.

After taking it, Gu Shuiquan looked at it symbolically, then pondered for a few seconds, and said, "I've unlocked it."

"Oh—?" The old lady stretched her neck long, making people worry about whether her head would fall off.

"So amazing, I deserve to be a well-known mystery novelist. My mind is really amazing." Mr. Aman was not stingy with praise and made Gu Shuiquan a well-known mystery novelist in advance.

The noble young master was a little more restrained, but he also opened his squinting eyes that had been closed before, fully demonstrating his excitement.

"It's still Brother Mizuki who is reliable, much better than a detective who is not worthy of his name." Ai Haibara's eyes flashed faintly. While praising Mizuki, he also complained about a rash guy who was still missing.
